About Data Scientist

Not all scientists spend their time in labs inventing. Data Scientists are named so because they can sort through large amounts of data and make it comprehensible for us laymen. If you enjoy working with numbers and derive satisfaction by making sense of chaos, here is a career for you to consider!

Data scientists collect, analyse and interpret data to understand market trends and help businesses as well as their customers. The role of a data scientist is actually an offshoot of a statistician’s role.Using advanced analytical tools like machine learning and predictive modelling, data scientists inform their inferences on howdata analytics drives business decisions that include changing business course/plan, improving products & processes, and creating new products and services. The primary responsibility of a data scientist is to identify ways to improve business decisions and help the organization gain competitive advantage.

Owing to the similarity in the nature of work and required skill sets, data scientists are often confused with data analysts. While data analystscollectand process data through statistical analysis, identify patterns and correlate data sets to determine business process improvements, data scientists do all that and much more. Based on the analytics, data scientists develop new algorithms for specific problems. They also explore data for insights on consumer behaviour and for market trend analysis.
